These techniques included controlling the radiation to preclude any stray emissions, minimizing stray emission, making detection difficult and permitting detection, but encrypting the contents.
Unintentional or stray emission is the transmission of signals in any direction except directly toward the intended recipient.
Unintentional or stray emission
may be defined as emission which is directed in any direction except directly toward the intended recipient.
Uncontrolled and stray emissions
of electrical and radio frequency interference across the spectrum cause vast problems, and those problems are increasing.
Kleerdex explains that newer MRI instruments produce stronger magnetic fields to produce clearer images more rapidly; however, these fields also intensify stray emissions
generated by the polymer used in the housings.
This increased intensity created its own challenge when it was found that stray emissions
from the plastic housings also increased in intensity.
